Optimal location and signal selection of UPFC device for damping oscillation

摘要: Unified power flow controller (UPFC) is used for controlling the real and reactive in transmission line bus voltage simultaneously independently. An additional task of UPFC to increase capacity as result oscillation damping. The effectiveness this depends on its optimal location proper signal selection system network. A residue factor has been proposed find controllers eigenvalue analyses are assess most appropriate input signals (stabilizing signal) supplementary damping control damp out inter-area mode oscillations. based relative participation parameters critical mode. simple approach computing proposed, which combines linearized differential algebraic equation model output equations. While a right-half plane zeros (RHP zeros) Hankel singular value (HSV) tools select receptive oscillation. placements have obtained base case dynamic contingences. method placement demonstrated practical network TNB 25 south Malaysian New England 39 system.
